IMPROVBD APPARATUS FOR .WASHING CRES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whomfit may concern Be it known that I, WILLIAM L. CARTER, of Marietta, in the county of Lancaster, and State of Penn- Figure 4, a plan view of the revolving ring with its Crushers, scraper-s, 85e.

Figure 5, a vertical section ofthe same, central shaft, and cylinders.

Figure 6, three of the Crushers, shown detached.

Figure 7 a set of the scrapers.

Figure 8, a set ofthe reversible Scrapers.

Figure 9 illustrates the double and single Scrapers or shovels and rack-teeth ou the centre-piece.

Figure 1 0 shows the plate and one detached shovel, with burr and washer.

The nature of my invention consists in providing revolving ling, with a series of rollers or crushers, Scrapers, shovels, and rake-teeth, made adjustable within a conic basin, into which the ore can be dumped from a cart, and subjected to being agitated, raked, and scraped in water constantly changing by a ow of clean water, While the muddy water is drawn olio from the centre, and so as to prevent any waste of 'ore and work the washed ore upward and through an open spout or chute to a hopper or place for its reception. Y

The same can be operated as a horse-power, or by steam or water-power.

To enable others skilled in the art to make and use. my invention, I will now proceed to describe its con,

struction.

ToJadapt the machine for transportation, the timbers are so framed and numbered that they can be readily'put together, as shown'in iig.- 1.

The four external post-s 4, have a pulley, al, on the top.

The inclined beams 6, being supported by the shorter posts 5, support the basin B, g. 3, which is stationary, with its bottom inclined t0 the ceutre,where it con nects with a cylinder, C, elevated above tlie dished 'cent1-e, with a cap, D, surrounding an'inner cylinder, through which the revolving shaft E passes, resting in a step on the centre of the cl'oss-pieces l and 2.

This shaft has a bevelled cog-wheel, c, below, and ts into a square collar in the central c'ap, with its ,sockets H, for the reception of the four radiatingarms I, bolted to the ring G. This ling rests on the pulleys a on the top of the posts 4.

'The outer and inner cylinders O c form an open receiver, being closed at the bottom, having a spout, F, which conveys the muddy water oii as it flows in above under the cap D. e The water is supplied from a tank, or otherwise, through the pipe Zaud enters an outer chamber, b 'b, and ilows through a strainer or perforations in the flange b, at this point forming the rim that surrounds the basin B, flowing down the inclined bottom toward the centre.

Fig. 2'shows a shaft, s, with its bearings, having a strap-pulley, S, at one end, and a bevelled pinion, meshing into the bevel-wheel e on the other end.

This imparts* motion to the central shaft E, and revolves the ring 'G and its appendages, whichV` consist of two sets of crushing-rollers M, iig. 6,' of any desired size or weight.

These rollers have arms L, with side bearings or ears, for rods or pivots r, which allow each itsr independent motion to surmount lumps of ore in crushing the same. f

Under these are supporting rods R, that prevent the rollers fromneedless action upon the bottom of the basin.

The other twosections or quadrants of the ring, alternating with the crushing-roller, contain Scrapers or shovels, shown by iigs. 7 and 8. Y

The cross-beams I, affixed to the ring' G and central collar H, are provided on the outer end with the V-shaped discharging-shovels V, rake-like teeth X, and oblique shovels XV, as likewise also on the crosspieces forming the .central collar.

One set of shovels, three, four, or six in number, gs. 8 and 10, are provided with-an upper bevel-edge and central screw-stem p, washer l, and burr k, by which they are secured in the block K.

The under side of this block has a heavy plate, Q,

with holes for the stem p, and cross-grooves to receivethe beveledge of the shovel and hold it firmly by means of the screw'and groovefltt-ing said shovel, and can be turned from one inclination or groove to'that of the other, for the purpose of regulating the operation of washing and discharging the ore,son1e ores requiring more and others less time to free them from impurities, and by this arrangement the discharge can be accelerated or retarded by the position of said adjustable shovels, working the ore upward' and outward to be received by the discharging-shovels V, or keptlonger under the rakesscrapers, and orushers, subjected to the action of the Water and the Washing, so that by a simple relaxation of the burr, ,the shovels can be setV for any particular kind of ore or bank, and

y are readily altered when the quality ofthe ore demands ments, spliced and bolted together by the radiating central pieces I, secured to the'central head H, ,which latter has spreaders or shovels so arranged, obliquely, as to work the ore anddirt outward from the central cylinder C, Where it is dumped from a cart or thrownA in from a platform above the machine, not shown.

This machine'can be adapted to suit any bank of ore that requires washing, and the' bottom of the concave basin overlaid With iron plates, or cast for the purpose, and the rollers, shovels, rakes, dnlyadjusted, will perform their Work with speed and satisfaction.

I am aware that rotating buddles or machines have been used so as to concentrate on the periphery of the floor as Well as in the centre, also revolving rakes and various devices of screens and washers; but I am not vaware of any device combined and operated substantially lin the manner shown and described,

What I'claim as my invention, and desire to secure by Letters Patent, is-

' 1. The arrangement and combination of the ring G with its radiating arms I, fixed in a central socket collar, H, and provided with the discharge-shovels V,

rake-teeth X, and central shovels W, together with the adjustable crushing-rollers M L, shovels U, supporting-rods R, and pivot-rods fr, the Whole mounted on rollers a., over a concave basin, B, with its flange b, substantially in the manner shown and for the purpose specified.

2. In combination with my revolving ring Gr and its appendages, the concave or conic basin B, with its central discharging-cylinder O surrounding the shaft E,

the straining-chamber b b, discharge-pipe F, from the, cylinder and spout Y, from-upper portion of the con-
